"The "ethnic" character of the term "wog" came into popular usage from the 1950s, when Australia accepted immigration of Italians, Maltese, Cypriots, Greeks, Lebanese who contrasted with the dominant Northern and Western European stock of the Australian population."

Note: Greeks and Italians.

My understanding of wog comes from the Australian use, so I'm still correct in that standing.

But okay. by the old british slang definition, dark skinned africans like some of the native egyptians would be "wogs".
